4 Games online
1 Game in alpha
1 Game in early dev
1 Game in research mode
I don't use SVN, It's all just in directories and I use a text file in the main directory as a to do list

I know my own code, I've pretty much been there and done that and I learn very little when it comes to using PHP or mySQL for the past couple years. At this point it's more about data entry then anything else, I know what to do I just need to type it.
However....
Running the games is another point entirely. Couple years back I needed to create an admin panel for quite a few admin's to run a game of mine (I think at max it was 6 ppl running the game). Basically I took what I had and re coded it from the ground up to be very modular (part of my node engine dream). Node Engine is on hiatus but the modular admin code became the back bone for all the games since then. Lets take my purchase of Galactic-Lords which had a VERY minimal admin panel. It took all of 2-4 hours to plug my admin panel into that system. If it's a game I created and doesn't have a lot of "one off" features it usually only takes an hour or two to plug the system in. That system includes searching by playerid, player, email, ip address or group (call it gang faction whatever). Features Side by side player account viewing, full editing, admin messages, reports, multi-detetion, game news, bug/issue tracker and just about anything else you would need to admin a game. This is by far the #1 reason we can run and maintain multiple games at once without being behind the keyboard all day

It also allows me to remember and keep track of my code because the administration is all the same on every game, all the tools are the same it takes very little thought.
Once I get some time I'm writing an article for bbg about how we run our games and will be showing screen shots of our iGoogle like panel that shows all our game statuses as well as one of the admin panels for the game.
